Call parking

[1] The “call park” feature is activated by pressing a preprogrammed button (usually labelled “Call Park”) or a special sequence of buttons.

At this point, the telephone system will often provide an option for the person to make an announcement through a public address system (often consisting of some or all of the telephone sets and or overhead paging speakers controlled by the telephone system).

An example would be at a grocery store where the bakery has a call parked.

A set time is then provided for any person to retrieve the call by dialing the extension number of the parked call on any telephone set.

Call parking is often useful in buildings with many offices or with more than one floor, and with most of the areas having access to one or more telephone sets.
